Thank you for the reply.
So you feel that the loads imposed from the pressures required for spinning will not be too much for the spindle bearings or the carriage and ways on these smaller machines?
I will lock the carriage to the ways during this proceedure and use a tool rest with several fulcrum points on it to turn the velocity stacks. After the stack is formed I plan to install the regular tool rest with a parting tool to remove the excess material from the mandrel.
